Best useing skrim tape on boards if you are plastering it. if you are useing paper tape you are best to go over it with easy fill and then a layer of joint cement the then sand it down and then primer for painting .hope that helps cheers eddie
Don't worry it sounds like some of your plaster perished if your walls are solid can be fix . take paper of leave it for few days to fully dry then check for any damp spots.
As long you prep it proper and good two coats will be fine.
